2. A certain transmission line operating at w = 106 rad/s has a = 8 dB/m, 3 = 1 rad/m, and Z = 60+ j402, and is 2 m long. If the line is connected to a source of 100° V, Z = 402 and terminated by a load of 20+ j502, determine: (a) The input impedance (b) The sending-end current (c) The current at the middle of the line (3 marks) (3 marks) (4 marks) Note: 1 Np = 8.686 dB
